Answer:

$68.05

Step-by-step explanation:

To find out what the total cost of the meal is, multiply 1.07 by 53 * 1.2. I'd multiply 53 by 1.2 first, then multiply the product of that by 1.07.

(53 * 1.2) * 1.07 (Convert 1.2 into 6/5, and 1.07 into 107/100.)

((53 * 6)/5) * 107/100 (Multiply 53 by 6 to get 318.)

318/5 * 107/100 (Cross cancel if needed.)

159/5 * 107/50 (Multiply 159 by 107 to get 17013.)

17013/(5 * 50) (Multiply 5 by 50 to get 250)

17013/250 (Divide 17013 by 250 to get 68.052)

68.052 (Round to the nearest cent)

The meal costs $68.05 in total.

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x) + c represents a vertical translation of the graph of f(x)

• If c > 0 then vertical shift up of c units

• If c < 0 then vertical shift down of c units

7

f(x) + 3 → vertical shift up of 3 units

Thus the point (- 3, 0 ) → (- 3, 0 + 3 ) → (- 3, 3)

8

f(x) - 5 → vertical shift down of 5 units

Thus point (4, - 2 ) → (4, - 2 - 5 ) → (4, - 7 )

-------------------------------------------------------------------------------

Given f(x) then f(x + a) represents a horizontal translation of the graph of f(x)

• If a > 0 then horizontal shift to the left of a units

• If a < 0 then a horizontal shift to the right of a units

9

f(x - 10) → horizontal shift to the right of 10 units

Thus point (3, 3 ) → (3 + 10, 3 ) → (13, 3 )

10

f(x + 4) + 5 → shift to the left of 4 units and shift up of 5 units

Thus point (6, 1 ) → (6 - 4, 1 + 5 ) → (2, 6 )

A study conducted in June 2015 examines ownership of tablet computers by US adults. A random sample of people were surveyed, and
Tatiana [17]

Answer:

a) The null hypothesis

H₀: P₁ = P₂

The alternative hypothesis

Hₐ: P₁ ≠ P₂

The proportion of the women population that own a tablet is P₁

And the proportion of the men population that own a tablet is P₂

b) The sample statistics are p₁ and p₂ for women and men sample proportions that own a tablet respectively.

p₁ = 0.4663

p₂ = 0.4330

The difference in sample proportion of tablet owners = p₁ - p₂ = 0.4663 - 0.4330 = 0.0333 (not 0)

Hence, the alternative hypothesis is true.

Step-by-step explanation:

The null hypothesis is the one that predicts no difference in tablet ownership.

The alternative hypothesis is the one that proves the initial theory of the survey that there is a difference in the proportion of men and women populations that own a tablet.

If the proportion of the women population that own a tablet is P₁

And the proportion of the men population that own a tablet is P₂

Then, the sample proportion of women that own a tablet = p₁

Sample proportion of men that own a tablet = p₂

The null hypothesis, H₀, stated mathematically, is

H₀: P₁ = P₂

The alternative hypothesis, Hₐ, stated mathematically, is

Hₐ: P₁ ≠ P₂

b) Like I stated in (a) the sample statistics are p₁ and p₂ for women and men sample proportions that own a tablet respectively.

From the data given,

p₁ = (235/504) = 0.4663

p₂ = (197/455) = 0.4330

In the sampled group, the women group have a higher proportion of tablet owners.

The difference in sample proportion of tablet owners = p₁ - p₂ = 0.4663 - 0.4330 = 0.0333

Hence, the alternative hypothesis is true.

Hope this Helps!!!
